You are writing a program for a car rental company. This company rents more than one type of vehicle to customers and the employees use programs written in Java to keep track of the cars for rental. Write the following Java classes to demonstrate inheritance and class design. (1) A Vehicle class that has a VIN (of type string) and gasTank () of type double, properties, a full constructor, and an abstract method called displayDetails() which returns a string. (2) A Car class that inherits from Vehicle also has a size (of type string) to tell if it is a subcompact, compact, or fullsized car and a full constructor. It should have a method called displayDetails() which returns a string and tells about all of its attributes. (3) A Truck class that inherits from Vehicle also has a bedSize (of type integer) to how big it is, properties and a full constructor. It should have a method called displayDetails() which returns a string and tells about all of its attributes. Make sure to have correct data types and correct access modifiers (public/private/protected) Create a Car object in main() and a truck object in main() to test your newly created class definitions.
